Using Penthouse Golden Egg during intercourse

The Penthouse Vibrating Golden Egg is fantastic. It can be used on my penis, on her clitoris, but our favorite way to use it is for my wife to lube it and insert it in her vagina. Then I insert my penis and we fuck with it vibrating inside. Fantastic orgasms for both of us.
It slips out easily from the lube and the cum. If your dick is very long you need to be careful not to push it in too deep.
I don't understand why more couples do not no this.
